摘要
本区大地构造位置处于天山―兴蒙造山区大兴安岭弧盆系扎兰屯―多宝山岛弧与海拉尔-呼玛弧后盆地分界处。区域上经历了多期构造和火山~岩浆活动,形成了大面积分布的花岗岩,新元古界~下寒武统嘎拉山组地层仅呈残留体状漂浮在晚三叠-早侏罗世花岗闪长岩和二长花岗岩之上,为在本区寻找斑岩型多金属矿床提供了有利条件。
The tectonic position of this area is at the boundary of the Zhalantun-Dobo Mountain arc and the HailarHuma arc basin in the Daxinganling arc basin of the Tianshan-Xingmeng orogenic area. The area has experienced a multistage structure and volcanic-magmatic activity, forming a large area of the distribution of granite, Neoproterozoic - Lower Cambrian Gala Formation Formation only residual body floating in the late Triassic-early Jurassic granite Diorite and monzogranite granite, which provides favorable conditions for the search for porphyry polymetallic deposits in this area.
